Solar Christmas lights are one of the most low cost Christmas decorations, helping the homeowners to save anywhere from around 100 W per each string of their lights. Another benefit of solar Christmas lights is that they turn on and off on their own, with the aid of a special photo cell making your Christmas even more magical.

Solar Christmas lights do not require an electrical outlet, they do not incur any energy costs, and they get charged in the daytime and turn on automatically in the evening. These lights eliminate the need for dangerous extension cords. These lights are a great and easy way to decorate trees around the house. Since there is no need for sockets, you can decorate any tree, no matter how far away it is from your house.

The principle of solar Christmas lights is a little solar panel with solar cells, capable of collecting solar energy and transferring it into regular electricity. Tiny solar panels can be placed anywhere, such as on the ground or on a tree branch. Four solar cells will allow the unit to completely recharge on a bright and sunny day.

The most sound are solar Christmas lights with specific polycrystalline solar cells, which charge well even on an overcast day, as well as, they emit brighter light.

How to calculate how long the lights will shine after the sun goes down? It is actually quite easy. Solar Christmas lights will usually stay on for about one hour at night, after being charged for about one hour in the daytime. Therefore, if the area where you live gets about eight hours of sun per day, you will also get about eight hours of shining lights in the evening.

Solar Christmas lights come in different colors and shapes. The most usual colors include red, yellow, green and blue, while the most common shapes include oval, round and teardrop shapes. The type of the light emitted can also be chosen to your preference, starting from a bright light, and to dim soft light.

Once Christmas is over, it doesn’t mean that you have to take your solar Christmas lights down. You can keep them in your garden, in order to; for example, decorate arches in your garden with this pleasant type of light. The lights can also be used for various other holidays, such as anniversaries and birthdays, as well as for lighting of pathways, porches, etc.

When choosing your solar Christmas lights, it is better to look for the lights with a rechargeable and replaceable AA battery. This type of a battery will allow you to enjoy your Christmas lights, even if they did not recharge on rainy or snowy days. All you would need to do is to charge batteries with a regular charger. Lithium batteries are not a good choice, since most likely you won’t be able to replace them, yourself.

You can have as many strings of solar Christmas lights as you want on the trees, and you will never have to worry about running the cords across your yard, never have to worry about turning the lights on and off, and most important, you will never have to worry about paying hundreds of dollars for electricity!

It might be a good idea to watch your yard for at least two or three days before placing your solar lights. The most important thing to note is that the area, where you want to place your solar Christmas lights, does not get a shadow cast. Another important thing to remember is that solar Christmas lights operate best when their solar panel is in direct sun throughout the day.
